Endymion FRS MK1 posted:I have the exact same setup. Just go into the bios, set the multiplier to 4.3, voltage offset to +0.05 or +0.10 (don't remember where mine is), you'll be good. Tried these settings with the +0.05 voltage offset and it looks like it's working out, ran IBT on Maximum setting and it passed with temps going 87/91/86/80. Well within the thermal limits of Ivy Bridge it looks like, but it's not like I'd ever get temps that high in the first place in a real life computing scenario. I tried 4.4ghz with +0.05 offset and it looked like my video drivers crashed before IBT finished one Linpack test, so I guess that means I need to bump up the voltage again if I want to aim for 4.4+.

You should make sure those numbers are safe, if i remember correctly, the 100% safe temps for Ivy Bridge are in the low 70s.

Biggest human being Ever posted:You should make sure those numbers are safe, if i remember correctly, the 100% safe temps for Ivy Bridge are in the low 70s. I've been reading up on temperatures, I'm going to run Prime95 now to see what kind of temperatures I get, my understanding is that IBT runs things hotter than you'll ever really see from actual computer use where Prime95 is a little bit closer to what one would expect from a real "full load" situation. The thermal limit for Ivy Bridge is apparently 105C but I obviously don't want to get near that. E: Prime95 core temps are much lower, I've had the hottest core peak at 79C but usually it's low to mid-70's with the other cores being low-70's to high 60's.

79 C is still too hot for regular use if you don't want to shorten chip's life. E: To clarify further, 105 C is the temperature at which the CPU will throttle itself and shut down to prevent imminent damage. For long-term damage, the limit is more around 68-72C.

A bit of very useful information via AnandTech, in a review of a boutique overclocked IVB system.quote:The main issue I have with our review unit is the 4.6GHz overclock on the Intel Core i5-3570K. Origin is pushing 1.4V through the chip under load and while in regular use (PCMark, game testing) the CPU never heats up too much, Prime95 sends the temperatures skyrocketing into the low 90s after just fifteen minutes. Worse, 1.4V is well beyond what conventional wisdom suggests is acceptable for Ivy Bridge. Origin argues that the typical user won't tax the CPU enough for this to result in reliability and longevity issues; their validation process through Intel states that at these settings and spending 70% of its lifetime under sustained load, the i5-3570K will last two and a half years. Emphasis added. If you work backwards, that's ~1.75 years running 24/7.

To be fair, 70% of time under full load on a gaming PC means you're gaming almost 17 hours a day. Also, 2.5 years is longer than their target demographic is likely to keep that computer, anyways. That said, I'd want some heavy duty cooling if you're going to overclock it THAT MUCH.

So, I have a question. In my excitement to OMG BUY A PC RIGHT NOW STEAM SALE YEAH, I specced out a bunch of parts, but somehow missed the part where the 3570K's selling point was overclocking. I had ordered a Cooler Master Hyper 212, for cooling, because why not, but I didn't really look for a case that was designed for cooling - mainly I looked for a non-hideous aesthetic, and some builder-friendly features. I settled on the Fractal Design Define R4. In the building thread, and in all the reviews I read, they said it was fine cooling-wise for stock configurations, which is what I was originally shooting for. Now that I know that my 3570K is designed to be overclockable, I kinda want to get some value out of that extra 30. With a CPU cooler like the one I purchased, and a case like mine, does anybody have a guesstimate at what sort of overclock I could expect to get while keeping my temperatures in check? Also, I've never been too good with thinking about airflow in a PC - would the temperature of the CPU have a significant impact on a graphics card [Or vice versa]? I'm thinking no, since the PCI-E slots are located below the CPU, and besides that, the cooler on my GPU vents outwards, too.

The spirit of overclocking is experimentation. Certainly there are far too many factors for us to give you hard numbers. Even if there were some known average we could give you, it could be tossed out the window by normal variations in the processor and motherboard. An excellent i5-3570K in a Define R4 could easily run faster and cooler than a poor i5-3570K in an Arc Midi, all else being equal. That's how much individual chips vary. Re: airflow and temperature concerns, the GPU temperature will affect the CPU to some extent through convection. However, the effect generally isn't large, and there isn't much you can do about it anyway. If your particular GPU is a model with a blower cooler (a reference card, for example), then case airflow is actually relatively unimportant as the blower will exhaust its own waste heat (hence the name). You really only have to be concerned about GPU-CPU heat intermingling when 1) the video card is crazy hot, like a GeForce 580, uses a cooler that doesn't specifically exhaust air (like most custom coolers - MSI Twin Frozr, Asus DirectCU, etc.), or both (GeForce 690 - exhausts half its moved air out the back); and 2) there is little capacity to move air through a large CPU heatsink, such as in a small mini-ITX case. In such cases, increasing airflow or even creative solutions like closed-loop liquid cooling to shift heat around before radiating are what you would do. But the Fractal R4 can handle things much better than a tiny mini-ITX case. Factory Factory fucked around with this message at 02:39 on Jul 28, 2012 |

I just got a new PC and I was not planning on getting a 'k' chip, but there was a sale at Microcenter that got me the i5-3570k and Asus P8Z77-V LX ATX LGA1155 for $255 total. Suffice to say, I am now planning on overclocking assuming the rest of my system is okay. PCPartPicker part list: http://pcpartpicker.com/p/dqBk CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor ($189.99 @ Microcenter) CPU Cooler: Cooler Master Hyper 212 Plus 76.8 CFM Sleeve Bearing CPU Cooler ($19.99 @ Newegg) Motherboard: Asus P8Z77-V LX ATX LGA1155 Motherboard ($124.98 @ NCIX US) Memory: Kingston Blu 8GB (2 x 4GB) DDR3-1600 Memory ($33.99 @ Newegg) Hard Drive: Western Digital Caviar Blue 500GB 3.5" 7200RPM Internal Hard Drive ($69.00 @ B&H) Video Card: MSI Radeon HD 7770 GHz Edition 1GB Video Card ($116.97 @ Newegg) Case: Thermaltake VL80001W2Z ATX Mid Tower Case ($24.46 @ Microcenter) Power Supply: Cooler Master 460W ATX12V Power Supply ($32.98 @ Newegg) Optical Drive: Lite-On iHAS124-04 DVD/CD Writer ($17.99 @ Newegg) Total: $630.35 I know that a few items on there are not the greatest. For example, I got the 212 plus instead of Evo because my company was buying this computer and they made some decisions I wouldn't have, but I couldn't argue. Same with case, memory, and power supply. Hopefully none of those things are major issues. So I am going to put this thing together tonight, but I have a question about thermal paste. I was going to just use the "Pea Method" but I read something in this thread about how my cooler would benefit from me applying the paste directly with a business card or something. Are there any thoughts on this? Can I use the pea method or should I do something else? Thanks for getting me started with the build and I'm sure I'll be back once the actual overclocking process begins!

I'm a proponent of the pea method. Pre-spreading is for lame dumbos. E: That said, for the 212+, there are gaps in the heatpipes that you should fill in with paste first so they aren't air gaps. A business card works great for that, just don't use it to spread paste over the heatpipes' contact surface itself. Factory Factory fucked around with this message at 23:34 on Jul 30, 2012 |

So, I'm using a CM212 Evo for my heatsink/fan combo. I'm noticing that my core temperature hits somewhere around 64 after about 20 minutes in Prime 95. Should I take off the arctic silver/reapply it/reseat the heatsink? Also, how tight should I screw down my heatsink mount? I was a bit worried about overtorquing the motherboard, and the manual wasn't really clear about how far down those weird spring/screws should be tightened down.

The thing's designed for about 80 pounds of mounting force, so those screws should be pretty tight, though not bottomed out or anything. You've got an i5-3570K, right? Is that at stock, or overclocked? If overclocked, what voltage/frequency are you at?

I run it with the top vents and side vent closed for that extremely quiet idle experience: 2500K @ 4.3GHz / Radeon 6950 (not blower style).

You should get a pretty healthy overclock out of that without pushing the voltage much, which should keep your temperatures in check. Ivy Bridge just does run hotter than Sandy Bridge. To be an absolute stickler, maybe that is a smidge high, temperature-wise. But it's not insane. Target ~80C for IntelBurnTest/OCCT Linpack, and your Prime95/real-world loads should be just fine.

You have to realize that Prime is a stress test that blasts your CPU to 100% load and RAM takes a beating too. That said, you will never actually see this sort of stress and load in real world everyday use... not during a game or anything really. That said, 64C is totally fine and nothing to be worried about at all. Tighten those thumb screws down all the way, IMO, so that the heat sink is totally flush, smooth, and evenly balanced on your CPU.

Or you might run Dwarf Fortress, which is famously intensive yet only single threaded, so it will push the limits of your overclock even if it isn't pulling down all the watts that Metro might. Or you could do CPU-based h.264 transcoding, which is basically as intensive as real-world loads get.

Actually prime95 is a pretty good indicator of a typical max stress situation. I've seen my CPU temps match prime95 levels during the second pass of an h264 encode. IntelBurnTest, on the other hand, is specifically designed to stress every single part of the CPU pipeline at once, and as a result, the temps are higher. e:f;b

The farther beyond spec you go, the less you can count on a poorly tested overclock. Please don't say stuff like this, it's walking potential newcomers to overclocking in the wrong direction vis a vis system stability. Prime95 is a representative high load, but remember that it exists as such because the Prime95 team needed a way for people to ensure that their systems weren't sending in bunk data for the calculations done in the search for higher (Mersenne, I believe?) primes. An unstable system eventually kicks an error and sends in an exciting new finding, which then wastes other systems' time because it turns out it was just a miscalculation. Anything Linpack-based is waaaay off the grid when it comes to real workloads, that's more what you're talking about (and, maybe ironically, less likely to find low-level instabilities because of the speed with which it exposes medium to high level instabilities - it shouldn't be used much with these more and more heat-sensitive components, get a 22nm transistor up to 75ºC+ and the resistance increase becomes dangerous to the nano-scale components themselves, can cause precipitous failure).

Let me rewind that last statement as well, ah, how exactly are you doing the overclocking? It could be idling normal if you're going with a constant voltage. If, however you're using the offset method it should be undervolting to .9V and downclocking to 1600mhz and idling cooler than that.

Sir Unimaginative posted:I set it to 42 and stuck with default voltages and apparently it only undervolts so low as 1.000. So, one-button overclock, and it is doing its power saving, that's good - but your temps aren't. If it's not underclocking to 16x (1600mhz) when idling, nearly 40ºC is a high idle, especially for the type of cooler that you're using, and could indicate some issue with its mounting (or, as you note, maybe just really bad airflow - that's the thing with the Xigmatek iirc, it isn't really optimized well as far as fin placement goes so a lack of airflow could mean that it needs a higher temperature delta in order to increase the efficiency of heat removal). Either way, those temps are 100% safe with Sandy Bridge, if a bit on the high side, and you can feel free to file all this away as academic if you'd like. You can run that setup for as long as you have the computer and expect no issues, I'd imagine.

Sir Unimaginative posted:Not a one-button overclock, and yeah it's underclocking at idle. I must have thought that goes without saying; sorry. Well, basic physics of taking heat from one thing and moving it to another thing is that the greater the difference in temperature, the quicker it happens. So while you're idling high, the performance under heavy loads is good. Living where you do, with high ambient temperature and expensive as poo poo electricity, maybe you're just gonna have to deal with high idle, it's not going to hurt anything, it's just a little weird. The load temperature is fine in Linpack and a bit high for Prime95, common advice here would be that you've got 10ºC of wiggle room with the multiplier and voltage with IBT, but I'm concerned about the Prime95 score. I don't get DRAMATICALLY different Prime temperatures, but they're consistently at least 6ºC lower than anything Linpack-based, and that's pretty important when you want to push your hardware as safely as possible. Well, if you want to go farther, I'd say the first thing to do is to get away from default voltage, if by that you mean "I changed the multiplier to 42 and didn't manually adjust the voltage," which it sounds like is what happened? Hell, your temps could just be due to an overzealous automatic voltage - what is your vcore under load as measured by HWiNFO64? Careful not to take the first values you see that relate to voltage, as those are VID in that monitoring utility, you need to scroll a bit to see vCore. 24/7 safe voltage is 1.38V for Sandy Bridge, but that assumes operational temps within safe parameters too, which Intel floats as 72.5ºC*. What's your motherboard? You're getting to the fun part of overclocking now.  *I think that's bullshit for a few reasons, not the least of which is they say the same thing for Ivy Bridge and there's no way the more sensitive and heat-issue-prone 3D transistors in IVB exhibit the same resistive, capacitive, or inductive properties, or experience electromigration exactly like Sandy Bridge, but they're being conservative and that's their prerogative, I'd estimate the real safe long-term temperature at 75-76ºC with infrequent excursions to 80ºC under extraordinarily heavy loads, within safe voltage parameters... Well, that's neither here nor there.

Two things on the temperature limit: 1) That's Tcase, a specification for the package/heatspreader temperature, not individual core temperatures. The idea of Tcase is that it's the target upper limit for 24/7 safety on the easily-measured heatspreader without overheating the cores. It's specified mostly for the benefit of OEMs designing as-cheap-as-possible cooling systems. We just kinda... use that as a target, because Intel said not to exceed it for a 24/7 safe overclock. If you're not exceeding Tcase, then the processor is "in spec" in that regard. 2) Tcase is specified by TDP in 1 C increments. 77W processors like Ivy Bridge i5/i7s actually have a specified Tcase of around 68 C, but the table actually lists Tcase figures below 65W and above 95W.
